Abstract

Thermal poling and depoling current for twin-hole fibers was measured. The current’s evolution was compared with electro-optic evolution. The thermally stimulated discharge efficiency was measured to be 5%. Atomic-force microscopy was used to study the HF-etched transverse sections of thermally poled twin-hole fiber. Thermal poling modified the etch rate in two rings about the anode hole. The outer ring was found to move with time, whereas the inner ring’s position was stationary. Results are explained by use of a space-charge model that comprises two components: movement of impurity ions and charge injection in which the charge injection component dominates the poling characteristics.
